What year is your car? If it's 95-99, start car, let it die, keep key in the run position until the theft light quits blinking (10 minutes or so). Turn car off, then start. If it's 2000+, Start, let it die, let it sit for 10 minutes, turn key off for 10 seconds, turn key to ignition for 10 minutes, off for 10 seconds, then another 10 minutes to ignition, and then off for 10 seconds. Should start.
